CAP-RETAINER FOR DEFOBMABLE TUBES.

Specification of Letters Patent.

Patented Jan. 2, 1917.

Application filed October 22, 1915. Serial No. 57,230.

To all whom it may concern -Be it known that 1, CHARLES CLARK, a citizen of the-United States, residing in the borough of Manhattan of the city of New York, in the State of New York, have invented certain new and useful Improvements in Cap-Retainers for Deformable Tubes, of which the following is-a specification, reference being had to the accompanying drawings, forming a part hereof.

In previous applications filed by the present applicant on August 27, 1915, SerhNo. 7,586, and on September 14, 1915, Ser. No. 50,560, there are shown and described retainers for the caps of deformable tubes comprising generally a link member or the equivalent, hingedly connecting the cap with the tube for the purpose primarily of preventing the loss of the cap.

The present invention consists of a novel construction for effecting the general purposes stated in said previous cases and has for its object the simplification and cheapening of the retaining devices for the cap.

The improved construction under consideration will be described in greater detail with reference to the accompanying drawings, in which- Figure 1 is a view in side elevation of a fragment of a deformable tube provided with a cap held thereon by the improved retaining devices, the cap being removed. Fig. 2 is a view similar to Fig.1 but showing the cap threaded into place on the neck. Fig. 3 is a detail view in perspective of the wire link for retaining the cap.

The deformable tube a is of the usual character and has threaded on its neck a an improved link I), which is preferably of spring wire, bent into a loop as at b, so as to permit it to be threaded along the threads on the neck a. The ends of this wire link I) are extended from the loop I) and in the plane thereof for a short distance to one side of the neck and are then curved to form eyes 6 for a purpose which will be described. It may be desirable. as illustrated, to make right angled bends b in the wire link before the eyes b are bent therewith a laterally extending lug (I by which is provided a suitable pintle (1 adapted to be engaged by the two eyes'b' formed at the ends of the link I) and afford a hinge line about which the cap may swing after being disengaged from the neck a" in the usual manner.

An improvement of notein the present invention resides in the provision of means for retaining the cap in the remote position shown in Fig. 1, so that it cannot rattle during use of the tube and, what is of greater importance, cannot drop'into the path of the outfiowing contents as would ordinarily be the case when the cap is disposed above the mouth as shown in Fig. 1. These means in the present form are embodied directly in the link I) and are made by giving a spiral twist to the ends of the link at the point where the eyes b are formed. This spiral twist in each eye in conjunction with the springiness of the wire itself offers a yielding resistance to movement of the cap 0 about the pintle d from the retracted position shown in Fig. l to closed position, and this resistance is sufficient to prevent all ordinary accidental rotation of the cap about the pintle.

In assembling the parts, after the link I) has been bent to proper form, the eyes 12 are engaged with the pintle (Z and the loop Z) is then threaded on the threads of the neck a until it passes beyond the end of the bottom of the threads on to the smooth metal immediately below the threads. 'Here the springiness of the wire holds the loop against movement upward on the threads during all ordinary rotationof the loop in either direction. When the cap 0 is threaded on to the neck the loop rotates idly with" it on the smooth portion of the neck. When the cap is unthreaded from the neck, the loop 6 rotates idly on the neck in the opposite direction. When the cap is rotated about the pintle d after being removed from the neck, it is thrown well back from the mouth and is held yieldingly in the position shown in Fig. 1, so that it cannot drop across the mouth of the passage-butmay be pressed to such position by the finger when it is to be returned to its place.

1 claim as my invention: 1. A retainer for the threaded cap of a vessel, comprising a link of spring Wire having a loop formed therein of a diameter to engage yieldingly the threads on the neck of the vessel and rest loosely therein and eyes formed in the-ends above the plane of the loop, and a lug formed integral With the cap and providing a pintle engaged loosely by the eyes to permit a hinged movement of the cap.

2. A retainer for the threaded cap of a vessel including a link of spring Wire on the'neck of the vessel, and a lug carried on the cap and loosely interengaged to permit the hinged movement of the cap awayfrom the neck, such link having eyes formed in its ends along a spiral twistto engage the lug, whereby the cap is held yieldingly away from the neck.

This specification signed this 21st day of October, A. D. 1915. v
